Alias for chained API calls?

Question

I have a query in which I need to chain api.Contact.getsingle twice, given that the entity I'm querying is linked to two different contacts for which I need to fetch the data.

The problem is that, given that both chained calls have the same name, it seems that the last one overrides the first.

Basically I need to do this:

$result = civicrm_api3('MyEntity', 'get', array( 'sequential' => 1, 'api.Contact.getsingle' => array('id' => "\$value.contact_id"), 'api.Contact.getsingle' => array('id' => "\$value.manager_id"), )); but with the ability to "alias" each chained call so that they don't get overridden

Is it possible to do it? If not, what a different approach would look like?

Thanks!

Answer 1

I believe there is a notation for issuing multiple chains by appending ".2", ".3", etc. For example, in api/v3/examples/Contact/ChainTwoWebsites.php, it uses:

'api.website.create' => array(
  'url' => 'http://civicrm.org',
),
'api.website.create.2' => array(
  'url' => 'http://chained.org',
),

As far as I know, there is no way to do aliases.

Note: The class which handles chaining is ChainSubscriber. In skimming that code, I don't see anything which explicitly processes the ".2" suffix as a number. It would be worth a try to use a prettier/symbolic suffix (e.g. api.Contact.getsingle.self, api.Contact.getsingle.manager) -
